Interphase & Prophase
True or False: Do the sister Chromatids seperate in Prophase?
False; The sister Chromatids seperate in Anaphase
True or False: During metaphase, the nuclear envelope begins to reform around the chromosomes
False; That is telophase
True or False: The spindle fibers disappear during telophase
True
true or false: Chromosomes contain the genetic material that is transmitted from parent to offspring
true
What is the end result of prophecy?
a cell ready to enter prometaphase/metaphase
What is the function of the centrosome in cell division?
The centrosome organizes the mitotic spindle, which is crucial for chromosome division during mitosis
During metaphase, where do the chromosomes align?
The Metaphase Plate
Telophase is often considered the reverse of which phase?
prophase
Which organelle is known for being the powerhouse of the cell?
Mitocondrea
What is the end result of metaphase
The alignment of all condensed chromosomes along the cell's equator, forming the metaphase plate
What are the X-Shaped structures visible in prophase?
Chromosomes
What structure pulls the chromatids apart during anaphase?
Spindle Fibers
Cytokinesis is the division of
cytoplasm
What are chromosomes made of?
threadlike structures primarily made of DNA tightly coiled around proteins called histones
what is the end result of anaphase
sister chromatids have fully separated, resulting in two identical, complete sets of chromosomes clustered at opposite poles of the cell, ready for nuclear envelope re-formation and cytoplasm division
Name the 3 stages of Interphase
G1 Phase, S Phase, G2 Phase
During anaphase, the pulling force of the spindle fibers shortens them, causing what to split?
The Centromere
What structure forms during plant cell cytokinesis?
cell plate
What is the primary role of an organelle
carry out specific, specialized functions within a cell
what is the end result of telophase
two new nuclei have formed around the separated chromosomes at opposite poles, the chromosomes begin to uncoil, and the mitotic spindle disappears
Explain what happens during Prophase?
The cell prepares for division by condensing duplicated chromosomes, the centrosomes migrate, the spindle forms, and the nuclear envelope breaks down.
They break apart at the centromere and become individual chromosomes
In animal cells, cytokinesis involves the formation of
A cleavage furrow
What is the primary role of a chromosome
to carry the genetic material of an organism, containing instructions for cell function, growth, and reproduction
what is the end result of interphase
a cell enters the Mitotic (M) Phase, which involves nuclear division (mitosis) and cytoplasmic division (cytokinesis) to produce two genetically identical daughter cells, beginning the cycle anew
